BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention relates to an ejection escape system for apassenger airplane, especially a system to increase the opportunity forpassengers to escape from an airplane through ejection of passenger seatout of the airplane.

[0003] 2. Description of the Prior Art

[0004] Due to rapid technology development and pursuit of quality life,recent technology has been used to develop many products, among whichtransportation tools are developed so that people can save a lot oftransportation time without the need to walk. The fastest currenttransportation tool with the longest travel distance is the airplane,which has lower probability of accident than other transportation toolslike cars and ships. However, when airplane accident occurs, ifpassengers fail to escape, which means passengers' lives are held bypilots, and if pilots mishandle or are unable to handle the situation,it will cause more serious injury and damage than car accidents and shipaccidents. Even if the airplane accident is caused by malfunction ofmechanical devices, all the passengers still can not escape and willshare the risk with the pilots.

[0005] Therefore, there are still some shortcomings for the currentairplanes, which need immediate improvement.

[0006] In view of the above shortcomings, the inventor was very eager toseek improvement. After many years of efforts, the inventor has finallycompleted the development of an ejection escape system for passengerairplanes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0025] Please refer to FIGS. 1, 2 and 3. The ejection escape system forpassenger airplane 1 in the present invention mainly includes:

[0026] A passenger airplane 1, which includes a body 11, a left topcabin cover 12, a right top cabin cover 13 and a cockpit 14, with anejection device 15 on the left top cabin cover 12 and the right topcabin cover;

[0027] A locking mechanism 2, which includes several buckle pins 21 andthe same quantity of buckle holes 22 at the corresponding position withcontrollable fasteners 221 controlled by a locking mechanism switch 23inside the buckle holes 22; and

[0028] Ejection escape seat 3, which includes a seat 31, an ejectiondevice 32, a safety belt 33 and a parachute 34, among which the ejectiondevice 32 is installed on the back of the seat 31, on the waist bucklebelt 331 of the safety belt 33 there are two corresponding shoulderbelts 332, on the rear side of which there is a back belt 333, while theparachute 34 is installed on the back belt 333, further, the two ends ofthe safety belt 33 are attached to the seat 31 through fasteners 334 andthe parachute 34 is installed on the back belt 333 of the safety belt33, besides, each ejection escape seat 3 is connected to an ejectionescape seat switch 35;

[0029] The locking mechanism 2 is installed on the left top cabin cover12, the right top cabin cover 13 and the corresponding sides on airplanebody respectively. The passenger airplane 1 has several buckle pins 21on the two sides of the left top cabin cover 12. At the connection ofthe right top cabin cover 13 and the left top cabin cover 12, there arethe same quantity of buckle holes 22 at the corresponding position tothe buckle pins 21 on the left top cabin cover 12. Each buckle hole 22has controllable fasteners 221. At the connection of the right top cabincover 13 and the body 11, there are several buckle pins 21. At theconnection of the body 11, the left top cabin cove 12 and the right topcabin cover 13, there are the same quantity of buckle holes 22 at thecorresponding position to the buckle pins 21 of the left top cabin cover12 and the right top cabin cover 13. The buckle pins 21 connect thebuckle holes 22 with retainers to secure the connection, so the left topcabin cover 12, the right top cabin cover 13 and the airplane body 11are connected. Further, each ejection escape seat 3 is attached to thecabin of the airplane 1 through the locking mechanism 2. Both thelocking mechanism switch 23 and the ejection escape seat switch 35 areinstalled in the cabin 14 of the airplane 1.

[0030] Please refer to FIGS. 4, 5, 6 and 7. When the airplane 1 is in anaccident, the pilot presses the locking mechanism switch 23 in thecockpit 14, so the fasteners 22 of the locking mechanism 2 at theconnection of the body 11, the left top cabin cover 12 and the right topcabin cover 13 depart from their original position and the buckle pins21 of the locking mechanism 2 are disconnected. Thus, the left top cabincover, the right top cabin cover 13 and the body 11 will separate. Thenthe pilot presses the ejection escape seat switch 35 in the cockpit 14of the plane 1, so the locking mechanism 2 between the ejection escapeseat 3 and the airplane 1 will be open. Meanwhile, the fasteners 334 atthe two ends of the safety belt 33 on the ejection escape seat 3 departfrom the seat 31 and the ejection device 32 on the back of the seat 3 istriggered to allow the passenger with the seat 31 and the ejectiondevice 32 to be ejected from the left top cabin cover 12 and the righttop cabin cover 13 to outside the airplane 1. When the ejection escapeseat 3 is ejected at the highest point and starts to drop, the parachute34 on the safety belt 33 will be open. At this moment, since the safetybelt 33 has been separated from the seat 31, the heavier seat 31 willdrop first and the passenger of the airplane 1 will drop slowly due tothe parachute 34. When the left top cabin cover 12 and the right topcabin cover 13 are departing from the airplane body 11, the ejectiondevice 15 ejects the left top cabin cover 12 and the right top cabincover 13 toward the two sides of the airplane 1 to prevent any danger ofthe left top cabin cover 12 and the right top cabin cover 13 hitting tothe airplane 1 as well as the ejection escape seat 3 hitting to the lefttop cabin cover 12 and the right top cabin cover 13, which may causeunwanted casualties. Besides, please refer to FIG. 9. The connection ofthe left top cabin cover 12 and the right top cabin cover 13 with theairplane body 11 can adopt hydraulic pressurization device 16 instead ofthe locking mechanism 2. When ejection escape is activated in theairplane 1, it only needs to open the left top cabin cover 12 and theright top cabin cover 13 by using the hydraulic pressurization device 16and then eject the ejection escape seat 3 out of the airplane 1.

[0031] Please refer to FIG. 8. The ejection escape system switch is inthe cockpit and controlled by the pilot. Particularly, the ejectionescape is allowed only when the airplane 1 is in emergency. Therefore,the electrical circuit for the ejection escape seat 3 is parallel tosave the operation time for the pilot, who then will have more time tosolve the problem in the airplane 1.

[0032] Further, at the locking mechanism at the connection of the lefttop cabin cover 12, the right top cabin cover 13 and the airplane body11, the original buckle pin 21 can be replaced by the buckle hole 22with controllable fastener 221, while the original buckle hole 22 can bereplaced by the buckle pin 21.

[0033] When the ejection escape system for passenger airplane iscompared with the conventional technology, it has the followingadvantages:

[0034] 1. It uses a locking mechanism to open the left top cabin coverand the right top cabin cover and uses ejection escape seat to eject thepassenger out of the airplane. Thus, when the airplane is in emergency,the passengers can escape rapidly and safely with minimized casualties.

[0035] 2. It uses ejection device to eject the left top cabin cover andthe right top cabin cover toward the two sides of the airplane, so thedanger of the left top cabin cover and the right top cabin cover hittingthe airplane can be avoided.

[0036] 3. It uses ejection device to eject the left top cabin cover andthe right top cabin cover toward the two sides of the airplane, so thedanger of the ejection escape system hitting the left top cabin cover orthe right top cabin cover can be avoided.

[0037] Many changes and modifications in the above-described embodimentof the invention can, of course, be carried out without departing fromthe scope thereof.
